"The ROCCAT Hiro Gaming Mousepad is a perfect size and constructed for durable, mouse friendly materials. The top silicon surface is super smooth for easy mouse movement and bottom is rubber so the pad won't go anywhere. Also, unlike cheaper cloth mousepads, it won't fray because of the materials used and it's bonded together extremely well. As well, this mousepad was tested with over 80 mice. This is a perfect choice for just about any gamer." ~3dGameMan.com
